A Study of Hereditary Predisposition to Cardiovascular Diseases
Because the many physicians and students of heredity have not been closely associated in finding that the causes of cardiovascular diseases might lie, in a large measure, to an inherited predisposition, this study has been undertaken; first, to contribute to several more case studies of cardiovascular diseases to the knowledge of heredity; second, to find if there is a possible successive occurrence of cardiovascular diseases in generation after generation; and third, to determine a possible mode of transmission from parents to offspring by an analysis of nine genealogies.

The Response of White Mice to Pituitary Gonadotropins of Fish
The purpose of this experiment is to determine if immature female white mice will react to the gonadotropic hormone from the anterior pituitary of several species of fish. If they can be shown to do so, a second purpose is to establish an assay unit for this fish gonadotropin in order that it may be used with predictable results in inducing extra-seasonal spawning for fresh-water conservation practices.

The Fecundity of the Bluegill (Lepomis Macrochirus) in Certain Small East Texas Reservoirs
A study of reproduction and spawning habits of the bluegill in a particular lake must include adequate samples for each period of the year. This will make it possible to determine the number of eggs in each spawn and the frequency of spawning. The number of spawns and average egg production for various sized fish shows the pattern of activity and makes possible further basic research.

In Vitro Determination of the Cellulose-Decomposing Rates of Twelve Denton County, Texas Soils
In this study twelve types of top soil were collected under aseptic conditions. The cellulose-decomposing rates of these were compared in order to determine the relative rates in the cellulose-decomposing potential of the microorganisms involved. Furthermore, this investigation is designed to acquire pertinent information on the rate at which natural cellulose materials are returned to available plant food.

Seasonal Survey of Actinomycetes in Twenty Denton County, Texas, Soils
This investigation has had for its aim a further study of actinomycete flora of twenty Denton County, Texas, soils. The problem has evolved itself into, first, a seasonal analysis for the number of actinomycetes in each of the twenty soils; second, a determination of the types of soils that contain the greatest number of actinomycetes in each cultivated and uncultivated land; third, a determination of soil moisture and pH; and fourth, an attempt to correlate these factors with the number of actinomycetes found in each soil type.

The Histological Effects of Injections of Fish Pituitary Extracts on the Testes of Male Frogs, (Rana Pipiens), and the Reproductive System of Immature Mice
The purpose of this investigation was first, to make a histological and cytological study of the testis of male frogs, Rana pipiens, and to determine if there were tissue or cellular changes as well as physiological effects caused by fish pituitary-extract injections. Second, to determine if injections of fish pituitary extract into immature female white mice caused histological changes in the ovaries and uteri.

Isolation, Identification and Cultivation of Four Phytopathogenic Fungi
This investigation includes a morphological and cultural study of four rather common pathogenic fungi one of which attacks Zinnia elegans, one Lagerstroemia indica, one Ligustrum lodense and one Euonymus japonica. The problem includes, first, a determination of the genera of these four fungi as revealed by their morphology in natural habitat; second, a determination of the growth and cultural characteristics of these on Cornmeal, Potato, Bean, Prune and Carrot agars; third, a comparison of the growth and cultural characteristics of these in natural habitat with the same on the various agars used; and fourth, an evaluation of the five artificial culture media in so far as their usage is concerned in the growth and cultivation of these four species of fungi.
